I didn't see a paywall, but I'm using uBlock Origin on Firefox so maybe it blocked out the paywall.

That's true of any galaxies which aren't gravitationally bound. At closer distances (tens/hundreds of millions of light years) gravity wins out over the expansion of space and keeps things together. At larger distances, the expansion of space wins out and clusters of galaxies will drift apart faster and faster until the combined speed of them moving away and us moving away from them will exceed the speed of light and we'll never see those galaxies again.

Our neck of the woods is called the Local Group because scientists are bad at naming things and includes the Milky Way galaxy, and the Andromeda galaxy, as well as between 50 to 80 more galaxies.

As for the black holes, yes, eventually all that will be left are black holes for trillions of years until even those evaporate which is often called the "Heat Death" of the universe. That is just a theory, but if it's true, it won't happen for 1.07x10^106 years. Considering the universe is only 13.8 billion years old right now, that's a very, very, very long time.

It really depends whether he got the devs of "Lutris, Heroic, Legendary, Bottles, etc." to agree to use the unified runtime before starting this project. As long as he gets most of the big players to join then it will actually become the only standard worth using.

It's important that they say structure because the scientific discovery is about how these galaxies are gravitationally bound in a cluster. That means that despite the expansion of space, these galaxies will never separate from one another, hence they are a single structure. It's a breakthrough discovery because every model of the universe we currently use says a structure this large is impossible.

context from the show Silicon Valley

As others have said here context is important. Are you reading just for fun? If yes, is it important to understanding what you're reading? If yes, look it up, otherwise either try to assume the meaning of the word through the context of the text or ignore it for now and look it up later.

I'm not a professional, but just an enthusiast but I'll try to simplify the article from my layperson perspective, so take my interpretation with a grain of salt.

The new theory seems to point to how Einstein's theory of gravity considers the "energy-momentum tensor" to be unchanged in all scenarios. The energy-momentum tensor describes the relationship of energy as it changes between various forms, for example a stick of dynamite exploding changes the chemical energy stored in the dynamite into kinetic energy - the force of the explosion - and if you calculated the energy of both they would be equal to the initial chemical energy stored in the unexploded stick of dynamite. Which is called the "law of conservation of energy", that energy cannot be destroyed, only transformed into a different form of energy.

The problem arises in high-energy situations where infinities start to appear in the equations. If you know much about math then infinities can break equations, and often in physics if there are infinities appearing in your equation then it usually means that you're missing something crucial. So scientists can use a technique called renormalization which can apply tweaks to equations to reduce these infinity spikes. At these high-energy situations described, renormalization fails and the equations can't be properly satisfied no matter how you tweak the variables. This is a big problem since a correct theory should be able to come up with answer for all possible situations that might arise within the system it's trying to describe without breaking.

Einstein's field theory - which is a model used to describe spacetime based on the distribution of matter within it - uses the curvature of spacetime, the relationship between stress and energy, and the cosmological constant. The new theory proposed suggests that adding to Einstein's field theory with math that accounts for the relationship between temperature and entropy, and the relationship between charge and interaction changes the equation in such a way that the infinities disappear, even at higher energy levels which traditionally break field theory, and most importantly that it's still consistent with observations.

Huh, TIL

The other advantage of buses is that they have a lot of inertia due to their mass. The most likely thing for them to hit is a car and most likely because that car made a mistake. The bus can easily push a car out of the way without losing too much velocity. The same is not true of your average civilian vehicle.

Such an advantage, theories suggest, came about due to males having to move around in large tracts of land while hunting, while women stayed closer to home as they foraged.

This is a popular misconception but there's a lot of evidence that shows early human societies were egalitarian and men and women equally participated in hunting and gathering. Especially after tools like the ahtlotl (a spear-throwing device) became common place.

Here's an article from NPR about gender equality in early humans: https://www.npr.org/sections/goatsandsoda/2023/07/01/1184749528/men-are-hunters-women-are-gatherers-that-was-the-assumption-a-new-study-upends-i
And here's a wikipedia article about the ahtlotl: https://en.wikipedia.org/wiki/Spear-thrower

The only thing that's different between Chrome and Firefox for the average user is that WebGL doesn't work (yet) in Firefox, which I know is technical, but it means some websites that need more graphics processing won't work in Firefox. Since WebGL is fairly new, I haven't run across it much, only once or twice.

The reason the bus driver has a seat belt and the kids don't is because the kids have a padded seat back in front of them to stop them from launching forward in a crash. The bus driver has nothing but glass and the open road in front of them to stop them from launching forward in a crash. And seat belts help protect the bus driver from the airbags as they deploy from the steering wheel which have been known to deploy so forcefully that if you're not wearing a seat belt they can kill you, and even in some extreme circumstances completely decapitate you.

Also as someone else pointed out the kids could get trapped in their seats in the event of a fire. The bus driver has a little seat belt cutting tool available to them, but in a fire they might not have time to cut 72 seat belts to free all of the kids on a big bus.

You might ask, well what if the bus rolls? It's pretty unlikely that the bus would roll because bus drivers are trained pretty extensively and have to go through periodic medical exams and driving exams to make sure they're capable of doing the job safely. Even if the bus were in a situation where it might roll, it's very bottom heavy so it would take quite a lot to get it to tip over.
